SHUTTLE-BOX MOTION.

Application filed. August 24, 1912.

To all whom it may concern Be it known that I, .losnrn: P. LANDRY, a citizen of the United States, and resident of Uxbridge, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Shuttle-Box Motions, of which the following is a specification.

This invention relates to looms, and has particular reference to the mechanism for operating the shuttle boxes of fancy worsted or fancy cassimere looms.

The principal object of the invention is to provide means whereby the shifting of the shuttle boxes may be controlled independently of the operation of the loom, so that if anything happens that might result in damage to a shuttle or shuttle box, the operator can instantly stop the shifting of the shuttle boxes and then stop the loom. Or if it is desired to weave for any length of time with filling or weft from only one shuttle, the result can be obtained by simply stopping the shifting of the shuttle boxes, leaving in operation only the shuttle of the box that is then in position for travel along the lay.

Another object is to provide improved means for insuring an accurate range of movement of the shuttle boxes.

T 0 these ends the invention consists in the construction and combination of parts substantially as hereinafter described and claimed.

Of the accompanying drawings: Figure 1 is a front elevation of those portions of a loom which embody my improvements. omitting such parts as are or may be of known construction. to avoid confusion of illustration; Fig. 2 is an elevation from the right of Fig. 1; Fig. 3 is an elevation of the controlling members carried at the other side of the loom from that shown in Fig. 2; Fig. 4 is an elevation from the left of Fig. 3; Fig. 5 is a plan view of the parts shown in the lower portion of Fig. 1; Fig. 6 represents a section on line 6-6 of Fig. 5.

Similar reference characters indicate the same or similar parts in all the views.

Portions of the frame of the loom are in dicated at 10, the lay 11, reed 12, and two shuttle boxes 13 at each end of the loom. Obviously there may be more than two boxes 13 at each end. The shuttle checks are indicated at 14-. The shuttle boxes move vertically in ways 15, under the control of a Specification of Letters Patent.

rod 16 passing through a guide bracket 17, said rod passing through a coiled spring 18 and having a roll 19 carried by the foot bracket 20. The roll 19 is engaged by an arm 21 (Fig. 2) of a rookshaft 22. There are two shafts 22, in alinement (Fig. 1), their meeting ends being supported in a bearing bracket hereinafter described. The inner end of each shaft 22 has an arm 23 (Figs. 1 and 6), slotted at 24 for the adjustable connection therewith of a link 25, the other end of which is connected to a lever .26 secured in an oscillating bracket 27 having its hub 28 (Fig. '5) mounted on a pivot pin 29. A roll 30 of lever 26 engages a cam groove 31 in ear The two gears 32 have their cam grooves so arranged. of course, as to alternately raise the shuttle boxes at the two sides of the loom. Said gears 32 are driven by pinions 33 carried by shaft 34: having a clutch member 35 splined on one end thereof (Fig. A cooperating clutch member 36 rotatable with a pinion 37 loose on shaft 34k is driven by means of the gearing 38, 39. The gear 39 is carried by a stud shaft having a bevel pinion l0 meshing with two bevel pinions 4:1, 42, loose on the vertical shaft 43 from which power is taken for driving both the shuttle box motion and the take-up motion of the loom. The reversing rod 14 is connected to the double clutch member 45 splined on shaft .43 whereby the latter may drive pinion l0 and (through the gearing 39, 38, 37) the clutch member 36 in either direction The splined clutch member 35 has a groove 46 (Figs. 3 and 1) which is engaged by a yoke 4-7 carried by a rockshaft 48 mounted in bracket arms and having an arm 50 connected by a link 51 with a bell crank lever 52 having a handle 53. Stops 54: limit the extremes of movement of the bell crank lever, a suitably secured friction spring 55 liiearing against one side of the lever holding the latter in either position of adjustment.

The meeting ends of the two shafts 22 are supported in a bearing 56 (Fig. 5) carried by a bracket 57 (Fig. 6) attached to a center frame member 58, one end of which is connected to a transverse frame rod 59.

When the loom is in operation, the normal positions of the parts shown in Figs. 3 and 4 will be as shown in those figures, the shaft 34E then turning and the shuttle boxes shifting for the usual purpose, through the action of the cam grooves in gears 32 and the levers 26. To interrupt such shifting however, at any time, the operative need only grasp the handle 53 (Fig. 3) and shift the lever 52 to separate the clutch member 35 from the clutch member 36. This can be done quicker than the loom can be stopped. After stopping the shifting of the shuttle boxes, the operator can stop the loom in the usual way, if necessary or desired. If stoppage of the loom is not efiected, weaving will continue with the one shuttle that is in the box in line with the lay at the time of stopping the box motion. The mechanism shown is a simple one for effecting this last mentioned result when it is desired to continue weaving for some time with but one of the plurality of shuttles carried by the boxes.

Having described my invention, I claim:

1. A loom having at each end a shuttle box arranged to reciprocate at an angle to the path of the lay, a controlling rod for each box, rolls carried by said rods, rock arms engaging said rolls to lift the rods and shuttle boxes, and power-driven means arranged for predetermined actuation of said rock arms, said power-driven means including a member manually adjustable, whether the loom be operating or at rest, to stop the actuation of said rock arms during subsequent operation of the loom.

2. A loom having at each end a shuttle box arranged to reciprocate at an angle to the path of the lay, a controlling rod for each box, rolls carried by said rods, rock arms engaging said rolls to lift the rods and shuttle boxes, power-driven means including disconnectible members and arranged for predetermined actuation of said rock arms, and means including a member manually adjustable, whether the loom be operating or at rest, to disconnect said disconnectible members to stop the actuation of said rock arms by said power-driven means upon subsequent operation of the loom.

3. A loom having vertically movable shuttle boxes at its ends, controlling rods for said boxes, rolls carried by said rods, two rockshafts inalinement having arms to engage said rolls, and mechanism for actuating said two shafts alternately, said mechanism including a single shaft, means including a clutch for rotating said shaft, gearing operated by said shaft, and lover connections between said gearing and the two rockshafts.

4. A loom having vertically movable shuttle boxes at its ends, controlling rods for said boxes, rolls carried by said rods, two rockshafts in alinement having arms to engage said rolls, and mechanism for actuating said two shafts alternately, said mechanism including a single shaft, means including a clutch for rotating said shaft, a pair of levers, slotted arms carried by the rockshafts, links connecting the slotted arms with said levers, and gears actuated by the shaft having the clutch, said gears having cam grooves for actuating said levers.

5. A loom having at its ends shuttle boxes mounted in ways, a rod connected to each of said boxes and having a roll at its lower end, rockshafts having arms engaging said rolls, cam-actuated levers, connections for transmitting motion from the levers to the rockshafts, said connections being adjustable to vary the amount of motion imparted to the rockshaft, and means independent of the loom driving mechanism for arresting the operation of the rock arms, whereby weaving can be continued with but one shuttle.

6. A loom having shuttle boxes mounted in ways, a rod connected to said boxes, and having a roll at its lower end, a rockshaft having an arm engaging said roll, a camactuated lever, and connections for transmitting motion from the lever to the rockshaft, said connections including a slotted arm of the rockshaft, and a link connecting said lever and slotted arm.

In testimony whereof I have allixed my signature, in presence of two witnesses.
